Finite-temperature spin diffusion in the two-dimensional XY model
Erik Fitzner, Byungjin Lee, Junhyeok Hur +4
We present a combined theory-experiment study to quantify spin diffusion in the square lattice quantum spin-1/2 XY model at finite temperature. On the theory side, we leverage a re…

Thermometry for a Kagome Lattice Dipolar Rydberg Simulator
Erik Fitzner, Igor Lesanovsky, Björn Sbierski
We propose an accurate thermometry approach for Rydberg atom tweezer arrays combining data from correlation and local susceptibility measurements with a theoretical high-temperatur…

Detecting nonequilibrium phase transitions via continuous monitoring of space-time trajectories and autoencoder-based clustering
Erik Fitzner, Francesco Carnazza, Federico Carollo +1
The characterization of collective behavior and nonequilibrium phase transitions in quantum systems is typically rooted in the analysis of suitable system observables, so-called or…
